I have a licensing question regarding Windows 11 Enterprise LTSC.

Our industrial machine is currently running Windows 11 IoT Enterprise LTSC 2024 (OEM license).

We confirmed the following:

  • Current Edition: IoTEnterpriseS
  • DISM /Online /Get-TargetEditions shows that EnterpriseS is a supported target edition.
  • The system is activated with an OEM IoT Enterprise license (OEM:NONSLP).
  • There is no embedded Windows Pro OEM key in the BIOS/UEFI.

Our machine manufacturer has requested that we change the operating system to Windows 11 Enterprise LTSC 2024 before they perform remote configuration and support.

However, we could not find any official Microsoft documentation explaining the licensing path for this scenario.

Could you please clarify the following questions?

  1. Is Windows 11 IoT Enterprise LTSC 2024 OEM a qualifying operating system for Windows 11 Enterprise LTSC 2024 CSP Upgrade licensing?
  2. If not, is there an official Microsoft licensing path to migrate from Windows 11 IoT Enterprise LTSC 2024 OEM to Windows 11 Enterprise LTSC 2024?
  3. Does Microsoft provide any official SKU, migration license, or conversion license specifically for this transition?
  4. If no migration path exists, what is the officially supported licensing method to replace Windows 11 IoT Enterprise LTSC 2024 with Windows 11 Enterprise LTSC 2024 while remaining fully compliant with Microsoft licensing?

We would greatly appreciate your guidance and any relevant Microsoft licensing documentation regarding this scenario.

Thank you very much for your assistance.I have a licensing question regarding Windows 11 Enterprise LTSC.

Yes, your device qualifies. In the Microsoft Product Terms for the Windows Desktop Operating System, the "Qualifying OS – Per Device Licenses" table explicitly lists Windows 10/11 IoT Enterprise under Windows Embedded Operating Systems as a qualifying operating system, including under the Microsoft Customer Agreement (MCA), which is the agreement framework used for CSP perpetual license purchases, and Windows Enterprise LTSC 2024 (Per Device) appears in the MCA availability table (available 10/24), so the officially supported path is simply to purchase a Windows 11 Enterprise LTSC 2024 per-device upgrade license through your CSP partner or another Volume Licensing program (EA, MPSA, Open Value, Select Plus) — no special migration or conversion SKU exists or is needed, because this is the standard upgrade-license model. Since IoT Enterprise LTSC 2024 and Enterprise LTSC 2024 are built from the same 26100 codebase and your DISM /Online /Get-TargetEditions already shows EnterpriseS as a valid target, no reinstall is required: once licensed, run slmgr.vbs /ipk <MAK from VLSC> (or the Enterprise LTSC GVLK M7XTQ-FN8P6-TTKYV-9D4CC-J462D if activating against KMS), and the edition will transform in place from IoTEnterpriseS to EnterpriseS, verifiable with DISM /Online /Get-CurrentEdition. The authoritative references are the Product Terms page for Windows Desktop Operating System (microsoft.com/licensing/terms) and the "Windows IoT Enterprise LTSC in Volume License" article on Microsoft Learn, which documents this exact key-based edition transformation mechanism. One compliance note to keep in mind: the underlying OEM IoT license stays permanently assigned to that device as the qualifying base, and the upgrade license is likewise non-transferable to other hardware, so document both against the machine's asset record before the manufacturer's remote work begins.
